IMPROVEMENT IN REFRIGERATORS FOR TRANSPORTING OVSTERS, &c.

Specification forming part of Letters Patent N 0. 142,703, datedSeptember 9, 1873; application filed June 25, 1873.

To all whom it may concern:

Be it known that I, JAMES C. JONES, of the city, county,and State of NewYork, have invented a Transportable Refrigerator, of which the followingis a specification:

This refrigerator is designed for the transportation of articles whilebeing kept in a state of preservation. It is specially adapted to thetransportation of shelled oysters to distant places; and consists of acask-like vessel or case and an inner removable concentric ice-chamber.The articles to be transported are introduced into the annular spacearound the ice-chamber. In the top of the refrigerator thus formed thereis an annular sub-head, in which fits a flange on the top of theremovable chamber. The latter is closed by a bung-piece on a cover,which seals the joint around it, and likewise secures a bung or stopplethat closes the filling-mouth of the refrigerative space.

In the accompanying drawing, Figure l is a central longitudinal sectionof the improved refrigerator, and Fig.2 is a sectional top view of thesame.

Similar letters of reference indicate corresponding parts in bothfigures.

A indicates the outside shell or case of the refrigerator. It is made ofcask-like construction,to facilitate its transportation from place toplace. B is the removable ice chamber or reservoir, which is arrangedconcentrically within it. It consists of a sheet-metal cylinder, closedat the bottom, and provided around its upper edge or mouth with anextended flange, C, which fits into a seat in an annular sub-head,D,provided in the upper part of the caskA. Under this sub-head there issecured a sheet-metal flange or ring, E, which projects under the flangeon the ice-chamber, and seals the joint between it and the sub-head, andlikewise supports the chamber in place. The lower end of thisice-chamber fits within a recess, a, in the bottom of the cask, wherebyit is held concentric within the cask. Instead of this recess, a ringmight be secured to the bottom for the same purpose. In this case Ishould make the ring flaring toward its upper edge, thereby the betterto center the chamber. The refrigerator is closed by a cover, G, whichlaps over the joint between the flange of the icechamber and its seat inthe sub-head of the cask, and is likewise provided with a bung-piece, I,which fits the mouth of the ice-chamber. bung-piece will be, inpractice, furnished with gaskets, to make good the joints in therefrigerator which it closes. A metal strap, J, crosses the cover G, sothat its ends project beyond it and fit bolts 1) b in the sub-head 1).Nuts applied to these bolts, outside the ends of the strap, secure thecover in place. The mouth at, through which the oysters or otherarticles are introduced to the refrigerator, is arranged in the flange(l of the ice-chamber, and the cover G retains a bung 0r stopple in it.This whole refrigerator is in reality a refrigerating cask. It might bemade tubshaped, if preferable.

The ice-chamber is made removable simply to facilitate the cleaning ofthe refrigerator after the removal of its contents.

The refrigerator thus formed is at once simple and cheap, and, moreover,can be transported with great facility from place to place. It isspecially adapted to the transportation of shelled oysters to distantplaces. It is, withal, very strong and durable.

What I claim as my invention is The transportable refrigerator composedof the cask-like case, the removable concentric ice-reservoir supportedby the sub-head G, and retained in place by entering a recess in thebottom of the case, as described, and the cover G, with its bung-pieceI, all combined and organized substantially as andfor the purpose hereinset forth.
